Subject: user of the jiffies rounding patch: Slab
From: Arjan van de Ven <arjan@xxxxxxxxxxxxxxx>
This patch introduces users of the round_jiffies() function in the slab code.
The slab code has a few "run every second" timers for background work; these
are obviously not timing critical as long as they happen roughly at the right
frequency.
